The repair for Tenga should work even without VRDB.
Maybe the infection is coming from the network? The Cleaner should certainly get rid of the infection (if you let it finish its scan and don’t work on the computer in between!) - but if the other computer is infecting the files back through open shares during the cleaning, it can’t do much about it. Try to disconnect the computers before starting the Cleaner (on both of them).
Hopefully you have more protection on the computer(s)
other than just an antiVIRUS !? How about antiSPYWARE,
antiTROJAN, & a 2 - way firewall ? You have failed to
mention the name(s) of the Operating System(s) ?
For Tenga, the Cleaner should be enough (and maybe slightly better, actually).
You should disconnect the computers from each other, and also from the rest of the network for that.
However, if you “control” only some of the networked computers, and have open shares on your disk for the other ones, it’s easily possible that the other ones will reinfect your files afterwards… I.e. it’s necessary that all the computers are clean and protected.
